Server-side ServicesOver the past few years, we have witnessed the rapid growth of server-side services for mobile developers, which claim to address similar storage, content delivery, and real-time functionality. A higher reliability and toolset can help developers reduce development time effectively, and it may be time to consider using server services in your next app. Here

9) Apache Spark
This is another big data framework that is becoming increasingly popular. The Apache Spark is a fast memory data processing engine with an elegant and expressive development API that enables data workers to efficiently perform streaming, machine learning, or SQL workloads that require fast iterations to access datasets.
You can use spark for ETL, machine learning, and data science workloads to the memory calculation of Hadoop.

Developing iOS projects inevitably uses third-party open source libraries, and the advent of cocoapods allows us to save time setting up and third-party open source libraries.Before using Cocoapods, the development project needs to use the third party open Source Library, we need1.

Personal advice is also best to specify a stable version number. This prevents you from always updating to the latest version when you run the pod Update command later (this is not necessary), and it also results in a non-un

With CocoaPods, you can define your dependencies, called pods, and manage their versions easily over time and across Devel opment environments.The The philosophy behind CocoaPods is twofold. Firstly, including Third-party code in your projects involves many hoops. For the beginning Objective-c developer, the project file is daunting. Going
IOS development: CocoaPods is a powerful tool for managing Objective-C third-party libraries.
1. CocoaPods is a software running in Ruby. It may take several minutes to install it. The installation name is as follows:
Sudo gem install cocoapods
2. If you want to generate a document for each third-party library, run
Brew install appledoc is optional.
After the installation is complete, the following message is displayed:
If your Ruby environment is not new enough, you may need to update it:
Gem
We often see two new ways to use it in C + + programs:NewA and new A (). So what is the difference between these two? The memory that the call to new allocates is sometimes initialized, and sometimes not, depending on whether the type of a is a pod (Plain old data) type, or whether it is a class that contains POD members and uses the compiler to generate a default constructor. Attached:
